Unlike many of the other devices, the CoPro uses both USB ports on the header. So if you don't see the CoPro on one row, put the header into the other row (port) ... one of the ports is for the CoPro and it's MCU and the other is for the USB hub.

I cleaned out a lot of junk in USBDeView, and I can now actively see the hub portion connect and disconnect as I plug in the USB connector.

However, I cannot get the other row to work.

The cable I purchased is a 5-pin, so I just pulled the last "no-connection" pin from the Molex and installed both possible ways into the "bottom" row.

I get no connect/disconnect sound when keeping the same orientation on the plug but just moving to the bottom row. When I rotate the plug 180 degrees (which I figured wouldn't work but had to try it), I get a "USB Device Not Recognized" from Windows.

Soooooo ... I missed the link to your external power supply.
It looks like it only provides power on the 12V rail. That ain't gonna work.
First, the CoPro microcontroller uses the 3.3V rail and the RGB LEDs use the 5V rail. The 12V rail is only used for the fans. You absolutely need to have all 3 present.

Looking at the wires, it looks like the SATA on that only has 5V and 12V rails. It may have 3.3V on the main but look at the photo with the SATA connector - there are only 4 wires going to the SATA connector and 2 of them are black. They are the same wires that connect to the Molex connector, which is only 5V and 12V.

The Commander Pro needs all three rails - 3.3V, 5V and 12V. You typically only get that from a full PSU.

If you can find something else that provides all 3 rails, that'd be an option. Note that this only applies to the CoPro; it doesn't apply to the Lighting Node Pro or RGB Fan LED Hub - they only need 5V and 12V rails.

Finally, success. After scrounging an old PS from my now non-functioning old NAS, and then confirming what I thought was a dead spare Commander Pro, I was able to get things running with a brand-new Commander Pro.

So ... question ... because I'm curious ... what do you need an external CoPro for? Are you running fans off of it?
